Abstract

L'invention concerne des articles absorbants imperrespirants tels que couches pour bébés, garnitures pour adultes incontinents, et surtout serviettes hygiéniques ou protège-slips. Selon l'invention, les articles comportent une feuille support perforée qui leur confère un caractère imperrespirant. Au moins l'une des couches imperrespirantes de la feuille support comprend une nappe tridimensionnelle résiliente, constituée d'un film polymère imperméable aux liquides et présentant des orifices. Ces derniers forment des capillaires qui ne sont pas perpendiculaires au plan du film, mais disposés selon un angle inférieur à 90 DEG par rapport audit plan.
